Deiotarus

Deiotarus (105 BC-40 BC) was a Chief Tetrarch of Galatia during the 1st century BC.

Biography
Deiotarus was born in 105 BC to the Tolistobogii branch of the Galatians, and he became one of the kings of Galatia. Deiotarus was a faithful ally of the Roman Republic, stopping Mithridates VI of Pontus' invasion of Phrygia in 75 and 74 BC. His most influential friend was Pompey, who rewarded Deiotarus' loyalty with more lands taken from Pontus. Deiotarus fought alongside Pompey during Caesar's Civil War, but he was forced to flee to Asia after the Battle of Pharsalus in 48 BC. He was saved from execution due to the advocacy of Cicero, although he lost his lands (but not the title of King), and he assisted Julius Caesar with defeating King Pharnaces II of Pontus at Zela in 47 BC. After Caesar's death, Mark Antony restored all of Deiotarus' lands to him, and he initially sided with Marcus Junius Brutus and Gaius Cassius Longinus during the Liberators' Civil War before going over to the triumvirs after the 42 BC Battle of Philippi. Deiotarus died in 40 BC.
